What is a debut without some lalalas and dadadas and woo woos?
This video contains K-Pop Girl Group debut songs with some silly phrases that are rememberable, usually these don't mean anything although some times the phrases have a meaning.

I legit didn't knew how to name these things, so I used what Wikipedia says https://en.wikipedia.org/wiki/Non-lex...

The MVs are from 2014 to today (February 2019). Apologies if I didn't include a group.
